Actually I was watching when they mentioned how you would pay for a few things. For instance the chapters (there will be 5) would be a payment for the next chapter, and with what Richard said it would be like doubling the game world. He also said if they added a city or something inbetween chapters it would be free and just something they were adding. Housing was if you had one on their servers there would be a charge since it would require upkeep. Didn't say how much though.

They also kept mentioning it was hard to keep up with the questions since that program was so poor and I can attest for that it was awful.
